The float 18 is permitted to descend to its lowermost position, the rod 17 is marked at theto'p of the portion 14:" and the rod '17 is then cutoff, as bynippers, slightly below the top of the portion ll.- When the operator des ires to determine aproximately the amountof liquid in thetank'he moves the that of Fig. 2' whereupon the rod "l7- rises under the influence of the float.-
